What bolt on will work now and later with a 408

I'm helping a buddy get his new ride under way. I want to do the mods that will work well as a bolt on car and then this winter when we do a 408. All I can really come up with are a pully, true duals and electric water pump. he already has a lid.

1 3/4 headers should work

i would definitely go with 1 7/8 if you plan to go 408 later.

I was figuring 1 7/8 as well. Isn't that too big for a bolt on car?

not if you plan on a 408 later, also get the FAST 90/NW 90 tb. Those will be good on the 408
